Put simply, AirTran is a very good airline with newer planes and great employees. However, they do have this annoying habit of constantly tinkering with their schedules. We always take the first flight out...they normally only move it by a few minutes either way. During the day they sometimes make drastic changes to flight times and sometimes cancel flights altogether. After you book keep an eye on their on-line schedules. They will notify you of changes, but the e-mail comes way after they have already changed the schedule.
